United States Patent O 3,472,148 VENTILATING APPARATUS Ronald Winnett, The Linden House Hotel, College Road, Epsom, Surrey, England Filed Oct. 16, 1967, Ser. No. 675,482 Int. Cl. F241? 13/08; E04f 17/04 U.S. Cl. 98-33 3 Claims ABSTRACT F THE DISCLOSURE Ventilating apparatus comprising an air-moving means for moving air into and/or out of a conduit system which comprises parallel longitudinal passages and apertures through which the air exhausts to or enters from the ambient at substantially constant rates over the length of the conduit system, by progressively blocking certain of said passages.

This invention relates to Ventilating apparatus and has for its object to provide an apparatus of very simple construction which can readily be installed in any building to suit individual requirements without requiring skilled labour, and to this end according to this invention there is provided Ventilating apparatus comprising a conduit for introducing air into and/or a conduit for extracting same from an interior space, in combination with means for moving air through said conduit or conduits, said conduit or each conduit being made up from a plurality of unit elements connected together and at least some of said unit elements being divided into separate passages one or more of which passages are blanked-oif in one or more of the elements and the elements each being so provided with apertures in communication with one of the passages as to cause air to pass through said apertures at substantially constant rates throughout the length of the conduit.

It will be understood that the unit elements can be connected together as required to suit the dimensions of the interior space, the obstacles encountered therein, th way in which it is desired to introduce and withdraw air and other such factors.

In a Ventilating apparatus which comprises a con uit for introducing air into and a conduit for extracting ame from the interior space, the means for moving the air conveniently comprises a unitary box or like housing divided into two compartments in each of which is provi ed a lian, the fans being adapted for drive so that one serves to move air to the space and the other to draw it from the space.

One embodiment of this invention will now be described in some detail by way of example with reference tothe accompanying drawing. This particular embodiment is primarily intended for use in Ventilating a single'room in a house or building.

In the accompanying drawing:

FIGURE 1 is a diagrammatic sectional View of a portion of the apparatus; and

FIGURE 2. is a diagrammatic sectional view of another portion of the apparatus;

In FIG. 1 the apparatus comprises a box-shaped housing 1 placed in an inconspicuous position in the room and divided internally into two separate chambers 2, 3, in each of which there is mounted a fan 4 adapted to be driven by an electric motor 5, the fans being of opposite hands as shown or, alternatively the drive to the two fans being in opposite senses. As a further alternative the two fans may be driven by a single motor via gears or belting. The housing 1 is provided with an inlet stub pipe 6 to chamber 2 and an outlet stub pipe 7 from chamber 3. The inlet 6 and the outlet 7 renpectively communicate with outside air by ducts 8 and 9 leading to a convenient ICC aperture which may be formed for example in a window or in a Wall.

On the other hand, the inlet 6 and the outlet 7 connect with the interior space of the room respectively via the chambers 2 and 3 and conduits 10 and 11 having apertures disposed as desired in the room usually on opposite sides thereof, the apertures being respectively to introduce air into and extract air from the room.

The conduits 10 and 11 are each formed from a plurality of modular unit elements of various required forms. Thus they may be formed of various lengths and shapes so as to allow for right angled or other turns to pass around picture rails and like parts which are normally outstanding from the walls in a room. By selecting the appropriate elements any desired conduits can be built up and assembled. The unit elements are formed at their ends so that they may be readily interconnected.

Alternatively, the elements may be formed so as to provide a false coving, picture rail, skirting board, frieze or the like of any desired pattern or appearance.

As shown in FIGURE 2 the conduit 10 is made up of modular unit elements 12 and 13, with certain of the elements 12 being variously apertured at 14 and being interconnected by the elements 13. The elements 12 are each shown, for example, as being divided longitudinally into three passages 15 which in the form of the succeeding elements as illustrated are blanked-off as at 16 in different manners so that in those modular elements as depicted by, the left-hand element 12 substantially a third of the air from the housing 1 passes out into the room through the apertures 14 in the upper passage 15 while the remainder of the air passes through the other by-pass passages 15 and the connecting element 13 to the form of modular unit represented by centre element 12. Here about half the remaining air enters the middle passage 15 and passes into the room through the apertures 14 formed in said e passage. Finally, the air passing through the lower by-pass asbge 15 in the centre element 12 continues through th next connecting element 13 and enters the lower passag 15 of the further modified form of modular unit as shown in the right-hand element 12 to enter the room through its differently positioned apertures 14. The conduit 11 is made up in a similar manner and in this way air is introduced into and extracted from the room at substantially constant rates along the entire lengths of the conduits 10, 11 in order to ventilate the room uniformly. i

The housing 1 containing the fans 4 may also include or be associated with meansfor filtering incoming air to remove from it impurities such as give rise to fog. The housing may also contain means for heating the air.

The embodiment illustrated is adapted for use either as a Ventilating or heating system and the housing 1 has its dividing wall 17 apertured and provided with a similarly apertured slidable valve plate 18. The inlet 6 and outlet 7 are closable by adjusting buttery Valves 19 and 20. By selectively opening or closing the inlet 6, the outlet 7 and the plate 12 it is possible either simply to recycle air through the housing 1 without introducing air into and expelling air from the system for quickly heating a room, partially recycling and replacing the air for maintaining a room heated and ventilated, or replacing the air without recycling.

In a modified form of the apparatus the housing 1 itself may be placed in a suitable aperture in a window or wall. Here the ducts 8 and 9 would be omitted and the inlet 6 and outlet 7 may take the form of adjustable louvre assemblies always directed away from each other so as to prevent air which has been expelled from the outlet 7 from entering the inlet 6.

While the invention has been described in connection with the introduction of air into and/or expelling same from a room in a house it should be understood that it could also be used for exchange of air from a normally heated room such as a living room to a normally unheated room, such as a bedroom, or to provide water tanks with protection against frost. The apparatus can readily be dismantled and by re-assembling the modular unit elements in different manner can be adapted to a different location.

I claim:

1. Ventilating apparatus comprising a conduit for inw troducing air into and/or a conduit for extracting same from an interior space, in combination with means for moving air through said conduit or conduits, said conduit or each conduit being made up from a plurality of separate basic modular unit elements connected together and at least some of said separate elements each including partition means dividing same into a plurality of separate longitudinal passages; said elements having means for longitudinal connection with complemental means of corresponding adjacent unit elements; means transversely blanking-oi one or more of said passages in one or more of the said elements; and air dispensing apertures so provided in each of the said elements in communication with one of the said passages as to cause air to pass through said apertures at substantially constant rates throughout the length of the conduit.

2. Ventilating apparatus as defined in claim 1, wherein said air moving means comprises a housing divided into two compartments in each of which is provided a fan, and the fans including driving means and being driven so that one serves to move air to the space and the other to draw it from the space.
